Assembly: mscorlib (in mscorlib.dll)
- Type: System::Double
A double-precision floating-point number.
The behavior of this method follows IEEE Standard 754, section 4. This kind of rounding is sometimes called rounding toward positive infinity. In other words, if a is positive, the presence of any fractional component causes a to be rounded to the next highest integer. If a is negative, the rounding operation causes any fractional component of a to be discarded. The operation of this method differs from the Floor(Double) method, which supports rounding toward negative infinity.
